A gas removal filter

Abstract

The application discloses a gas removal filter and relates to the technical field of filtering equipment. The filter comprises a cleaning mechanism. When the flow and flow rate of oil suddenly increase, the liquid level is rapidly lifted, the buoyancy of a floating ring and a floating plate is increased, and the lower scraper and the upper scraper are driven to scrape off the impurities adhered to the side surface of a filter cylinder, so that the filtering channel is kept unobstructed. Part of the oil enters a spiral channel in the filter cylinder. Under the action of centrifugal force, the oil can be thrown out from a circular hole, an outer side edge hole and an inner side edge hole. Under the action of gravity, the oil is beaten on the spiral channel or the flowing oil. The spiral channel increases the probability of the oil completing the gas removal process and improves the gas removal effect.

[0045] The bottom cleaning piece 432 comprises a limiting cylinder 4321, the top of the limiting cylinder 4321 is fixedly connected with a sealing top plate 4322, the top of the sealing top plate 4322 is fixedly connected with the inner wall of the gas removal filter tank body 1, the inner wall of the limiting cylinder 4321 is slidably connected with a second moving rod 4323, the bottom of the second moving rod 4323 is fixedly connected with a floating plate 4325, the bottom of the floating plate 4325 is fixedly connected with an elastic rope 7, the bottom of the elastic rope 7 is fixedly connected with an upper scraping plate 4326, the upper scraping plate 4326 is provided with an arc-shaped hole 4329, both ends of the upper scraping plate 4326 are fixedly connected with sliding blocks 4327, the top of the sliding block 4327 is fixedly connected with a resistance reducing plate 4328, the sliding block 4327 is provided with a square hole 8, both ends of the sealing top plate 4322 are respectively provided with sealing side plates 4324, both ends of the sealing top plate 4322 are respectively fixedly connected with the side close to the sealing side plate 4324, the side close to the sealing side plate 4324 of the two sealing side plates 4324 is provided with a sliding groove 6, the sliding groove 6 is slidably connected with the sliding block 4327, the bottom of the floating plate 4325 is fixedly connected with a supporting rod 9, the bottom of the supporting rod 9 is fixedly connected with the top of the lower scraping plate 4319.

[0046] When in use, the flow and flow rate of oil at the inlet 2 suddenly increase, and the oil hits the side of the filter cylinder 41. Due to the increased impact force, part of the impurities is easily plugged into the filter hole, causing the filter cylinder 41 to be blocked. The impact side of the filter cylinder 41 and the two sealing side plates 4324 form a relatively closed narrow space. After a long period of use, the filter hole at the impact side and the bottom of the filter cylinder 41 is easily blocked. At this time, the amount of oil stored per unit time is greater than the amount of oil flowing out. At this time, the liquid level between the two sealing side plates 4324 rapidly rises, and the buoyancy on the floating ring 4316 gradually increases. The floating ring 4316, together with the connecting rod 4318, the lower scraper 4319, the support rod 9, and the first moving rod 4312, moves upward. The first moving rod 4312 passes through the inside of the limiting plate 4314 and is in sliding connection with the inside of the limiting plate 4314. The first moving rod 4312 can only move in the vertical direction under the limiting action of the limiting plate 4314. Due to the large surface area of the floating ring 4316, the buoyancy is large, and the support rod 9 will also vertically move upward against the upper scraper 4326. However, since the lower scraper 4319 is located at the bottom of the gas removal filter tank 1, the lower scraper 4319 is subjected to a relatively large pressure of the liquid, and the resistance to upward movement is large. The lower scraper 4319 is a structure with a raised middle portion, and the cross section of the lower scraper 4319 is similar to a triangle. An arc side of the lower scraper 4319 is provided with a liquid outlet hole 5, and the arc side is relatively thick. The liquid outlet hole 5 will not cause the rigidity of the lower scraper 4319 to be too weak. The triangular protruding structure and the liquid outlet hole 5 can both reduce the resistance to upward movement of the lower scraper 4319. When the lower scraper 4319 moves, it can scrape off the impurities adhering to the side of the bottom of the filter cylinder 41, increase the filtering effect of the filter cylinder 41, and speed up the passage of oil through the filter cylinder 41.

[0047] The liquid level between the two sealing side plates 4324 rises, and the floating plate 4325 moves upward under the support of the buoyancy and the support rod 9. The floating plate 4325 pulls the elastic rope 7, the elastic rope 7 is straightened, and the elastic rope 7 pulls the upper scraper 4326 and the sliding block 4327 upward. The upper scraper 4326 scrapes off the impurities blocked on the filter cylinder 41. The oil flushes the impurities blocked in the filter hole into the filter cylinder 41. This part of the impurities is small in diameter and easily flows out of the filter cylinder 41 with the solution. At this time, the partially blocked filter hole at the impact side of the filter cylinder 41 is opened, and the filtering effect is improved. The top of the sliding block 4327 is provided with a resistance reducing plate 4328. The resistance reducing plate 4328 is shaped like a roof, and the upper scraper 4326 and the sliding block 4327 are respectively provided with an arc-shaped hole 4329 and a square hole 8. The arc-shaped hole 4329 and the square hole 8 provide a passage for the solution, and they can both reduce the resistance to upward movement.

[0048] The flow rate and flow increase, the oil hitting the filter plate in unit time increases, it is easy to make the air in the liquid unable to escape, part of the oil liquid has not completed the degassing process, part of the oil enters the spiral channel 421 inside the filter cylinder 41, the oil moves downward along the spiral channel 421, the circular holes 422 opened in each layer of spiral channel 421 are staggered, the oil can directly fall from the circular holes 422, and under the action of gravity, it is beaten on the spiral channel 421 or the flowing oil, so that the oil and gas are separated, and the edges of the inside and outside of the spiral channel 421 are respectively provided with outside edge holes 423 and inside edge holes 424, the density of the outside edge holes 423 and the inside edge holes 424 decreases from top to bottom, and the number of the outside edge holes 423 is greater than that of the inside edge holes 424 on the same layer of spiral channel 421, most of the oil is thrown out through the outside edge holes 423 under the action of centrifugal force, and these oils collide again, so that the gas-liquid is separated again.

[0049] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art in the technical range disclosed by the present application, according to the technical scheme and the inventive concept of the present application, equivalent replacement or change, should be covered in the protection scope of the present application.
